Radium Engineering Crankcase Fluid Lock Catch Can Kit for Honda S2000

If you own a Honda S2000 from 2000 to 2009, you’re in for a treat with the Radium Engineering Crankcase Fluid Lock Catch Can Kit! This kit is tailored specifically for the 2000-2009 RHD and 2006-2009 LHD models. Just a heads up, if you have a 2000-2005 LHD model, you'll need to remove the cruise control module for compatibility. Otherwise, check out our dedicated page for the 2000-2005 Honda S2000 LHD Catch Can Kit.

Why You Need an Oil Catch Can

When it comes to performance vehicles, an oil catch can is a must-have. It helps protect your engine from the crankcase blow-by that can build up from spirited driving. This excess oil-saturated air can find its way back into your air intake, which isn’t good for performance. With Radium Engineering's catch cans, you’re getting large 10AN ORB ports, a 4AN ORB drain port, a two-step oil separation baffling system, and an O-ring sealed dipstick. Talk about quality!

S2000 Catch Can Kits

Radium Engineering offers two separate oil catch can kits for the S2000, available for purchase individually or as a pair. These kits are designed not to vent to the atmosphere (VTA), making them emissions-friendly and track legal. The closed-loop system routes clean, filtered air back into the engine to be burned, promoting negative crankcase pressure for optimal performance. Plus, this setup helps keep unwanted oil vapors out of your cabin—win-win!

How the 20-0097-FL Crankcase Catch Can Kit Works

The 20-0097-FL Crankcase Catch Can Kit is designed to run inline with the 1/2" valve cover breather port. At lower loads, it maintains atmospheric pressure, but when you push your engine to its limits at wide-open throttle (WOT), it creates a vacuum. This is crucial because it prevents unwanted crankcase vapors, unspent fuel, and oil sludge from entering your air filter intake pipe. If you’ve got a turbocharged or supercharged engine and you’re noticing oil buildup in your intercooler, this catch can is a game changer—it helps maintain the thermal efficiency of your heat exchange process.
